BUTTON.

SPECIFIGATION forming part of Letters Patent No. 660,127, dated October 23, 1900.

Application filed April 16,1900. Serial No. 12,985. KNO model-l T0 all whont it may concern:

Be it known that I, EUGENE W. SILsBY, a citizen of the United States, residing at La Grange, county of Cook, State of Illinois, have invented certain new and useful Improvements in Buttons, of which the following is a specification, reference being had to the accompanying drawings,forming a part thereof.

In the drawings, Figure 1 is a diainetric section of my improved button. Fig. 2 is a similar view showing the parts loosely assembled and imperfectly clenched to permitthe several elements to be clearly distinguished and their character observed.

My improved button comprises a back shell A, having a central aperture a for the tuft b, which is formed at the center of the tuft disk B, and a face element 0 of non -metallic plastic sheet material, such as celluloid or other substance, which may be similarly worked. The back shell A is preferably cupped or provided with a marginal flange A, and the face element 0 is extended to form a peripheral binder encompassing the margin of the back shell, including the flange A when present. The face element is sharply depressed within the margin of the face side of the button, forming an angular feature a, causing the peripheral portion to stand out as a head 0, and by this means the grip of the peripheral binder, which is constituted by the outer marginal portion of the face element folded about the margin of the back shell, is made adequate to securely bind all the elements of the button together. Besides this I gain another advantage from this angular feature, for by extending the tuft disk so that it is gripped by the angle of the face element at this point I prevent it from pulling out, as it would be liable to do if it were held only by the general pressure of the face and back elements on its opposite surfaces. When the back shell is cupped or flanged as shown, its flange extends up into the head 0 and supports the latter, but since it would be liable to cut the bead in the process of manufacture or subsequent use, and since the button has no cloth-face element which if present might be extended to cover the edge of the back shell and protect the plastic-face element, I extend the tuft disk B as shown, so that it covers the edge of the flange of the back shell, filling out the cavity of the bead and fortifying the latter and at the same time afiording the protection from the edge of the flange A. A further feature which may be employed with ad vantage consists in depressing the face element 0 at the center opposite the tuft-aperture a of the back shell, as seen at 0 so that it binds the tuft disk to the back shell by pressure at the margin of said tuft-aperture.

I claim-- 1. A button, consisting of a cupped or flanged and apertured back shell; a face ele- -ment of non-metallic plastic sheet material which is extended to form a peripheral binder encompassing the flange of the back shell and clenched onto the latter, and depressed within the flange of the back shell; in combination with a tuft disk, lodged between the back shell and the face, protruded at the aperture to form a tuft and in contact with both the shell and the face at the depressed portion of the latter and the immediately-opposed portion of the former; whereby said tuftis gripped and held directly between said back shell and face.

2. A button, consisting of a cupped or flanged and apertured back shell, a tuft disk lodged therein and adapted to protrude the tuft at the aperture; a face element covering the tuft disk; and a peripheral binder of non- 1 metallic plastic sheet material which extends from the face element over the flange of the back shell, forming a hollow bead over the edgeof such flange and which is clenched onto the back of the shell, the tuft disk being extended to cover saidedge of the flange within the hollow bead, to fortify the same and guard the plastic sheet material of the binder from the edge of the flange.

3. A button, comprising an'apertured back shell; a tuft disk adapted to protrude at the aperture; a face element which is depressed opposite the aperture to bind the tuft disk at the margin of such aperture to the shell; and

a peripheral binder which secures the face and back shell together.

4. A button, comprising an apertured back shell; a face element which has a depression opposite the aperture in the back shell; a tuft disk interposed between the back shell and the face element and in contact with both said shell; a tuft disk, adapted to protrude the tuft at the aperture; a face element of nonmetallic plastic sheet material which is extended integrally over the periphery of the back shell and clenched onto the back thereof, forming a peripheral binder securing the parts Together, such element being depressed abruptly within the margin of the face side of the button forming an upraised peripheral bead and an angular junction of such head with the face, the tuft disk being extendedso as to be gripped between such angular feature and the inner surface of the back shell.

6. A button, comprising an apertured back shell, a tuft disk, and a face element of nonmetallic plastic sheet material between which and the back shell the tuft disk is inclosed, the face element being extended to form a peripheral binder encompassing the edge of the back shell and clenched onto the back thereof, such element being depressed abruptly within the margin of the face, forming an angular feature substantially opposite the edgewhich is clenched on the back, the tuft disk being extended between said angular feature and the clenched edge of the binder.

7. A button, comprising an apertured back shell; and a face element of non metallic "plastic sheet material which is extended to form a peripheral binder encompassing the edge of the back shell and clenched onto the back thereof; said face element being do pressed angularly within the margin of the face, forming an angular feature substantially opposite the edge which is clenched on the back; and a tuft disk inclosed between the back shell and said face element, and in contact with both said parts at said angular feature of the face element and the opposed
